Might alien life be buried under too much ice to phone Earth?

Why haven’t we had alien contact? Blame icy ocean worlds perhaps.

It’s only recently that astronomers have come to appreciate how common oceans are in our solar system; evidence for them can be seen on several moons of Jupiter, Saturn, and Neptune, and even distant Pluto. These worlds all have water ice as a major component of their crusts, which forms towering mountains and cracked canyons on their surfaces but melts into liquid water at lower depths. Hydrothermal vents on these ocean beds might pump nutrients into their surroundings, similar to ecosystems at the bottom of Earth’s oceans. Such nurseries for life—shielded from space by a thick ice shell—might even be more productive than our own exposed environment.

And should living organisms on icy ocean worlds evolve into intelligent creatures, they probably wouldn’t know the night sky as well as us humans. Perhaps the equivalent of their “space program” would simply be boring through to the frozen surface of their planet. Learn more here.

    Less of volcanic activity is actually to blame. Due to volcanic activity,green house gases might form atmosphere on these icy planets and eventually melts these icy layers and might give a chance for origin of life.
